''The Journal of Neuropsychiatry and Clinical Neurosciences, 3''(2), S57-S60.</ref> The scale is generally used to track aggression and aggressive acts over time, typically at one week intervals.<ref name=":1" /> It has since been used to measure the efficacy of therapy and drug treatments on aggressive behavior in clinical settings.<ref>Oliver, P.

In a study conducted by Chinese researchers in 2009, the Modified Overt Aggression Scale was found to be both reliable and valid.<ref name=":0" /> The results from the study concluded there was high reliability,<ref name=":0" /> meaning the scale consistently measures the levels of aggression in each category. The MOAS is also confirmed to be valid,<ref name=":0" /> meaning the scale truly measures what it
In 2009, a study conducted by Ira L. Cohen and her associates studied characteristics, such as aggressiveness, in people with [[Intellectual disability|intellectual disabilities]] (IDs). The MOAS was used and researchers reported it being "a reliable and valid measure of aggressiveness in this population."<ref name=":2">Cohen, I. L., Tsiouris, J. A., Flory, M.
